AXYZ is rotated 180°.<br> What are the coordinates of point X'?

vredina [299]

<h3>Answer: (4, -1)</h3>

Reason:

When rotating a point 180 degrees around the origin, you use the rule

$(x,y) \to (-x,-y)$

We flip the sign of each coordinate from positive to negative or vice versa.

The point X is at the location (-4, 1). Rotating this 180 degrees will get us to X'(4, -1)

Hence the correct final answer is:

$\frac{4y^3}{x^3}$

Further explanation:

Given

$Line\ 1: \frac{4}{1}.\frac{x^{-2}}{1}.\frac{1}{x}.\frac{y}{1}.\frac{1}{y^{-2}}$

The student made the mistake in line two. There was no need to move 4 in the first term, from numerator to denominator

The correct line 2 will be:

$Line\ 2: \frac{4}{1}.\frac{1}{x^2}.\frac{1}{x}.\frac{y}{1}.\frac{y^{2}}{1}}\\Line\ 3: \frac{4y^3}{x^3}$

Hence the correct final answer is:

$\frac{4y^3}{x^3}$
